The new feature, available for Android and the iPhone, automatically uploads photos taken on a smartphone to a private album on a user's Facebook profile. Those photos can then be removed, kept private, or shared publicly. A total of 2GB worth of photos can be stored from mobile devices.

Facebook said it began testing photo sync in August and "will continue to make it available to more people."

Don't like the idea of your photos automatically sent to your Facebook profile? No worries, users don't have to activate the feature. But, if you want it, you'll need to use the latest version of the Facebook app, and turn on the syncing manually.
